Ice-breath

I'll cryo freeze you with some English beef!

Ice-breath is an ability that several Transformers with reptilian beast modes have installed in themselves for combat in their alt modes.

Fiction

Beast Wars

After becoming a Transmetal 2 dragon, Megatron possessed a new ability called Blast of Cold—shooting sub-zero blasts, in one word, ice-breathing. He also had the ability to shoot flame, which was called "Blast of Flame". Megatron likes to keep his enemies on their toes. Yessss... Master Blaster

Universe

Cryotek is capable of firing supercooled blasts of ammonia from his dragon head in both robot and alternate mode. This ability allows him to either freeze or desiccate his target. Cryotek's Universe profile

Shattered Glass

Goryu used his ice-breath against Sideswipe for bothering his buddy Slugfest. Dungeons & Dinobots

Notes

• Goryu's ice-breath is the mirrorverse answer to fire-breath possessed by Dinobots in Generation 1 and other normalverses. It may or may not be a reference to the comic book supervillain Bizarro, an imperfect clone of Superman, who famously packs a number of superpowers which are "reversed" versions of Superman's, e.g. cold vision to his heat vision, flame breath to his frost breath, etc..
